SPRING CLAMP.

Application led January 27, 1928. Serial No. 615,225.

15 Drawings.

In the drawing-' Fig. 1 is a perspective view of a clamp embodying my invention.

Figs. Q, 3 and 4 are plan views of said clamp in various adjustments.

Description. l have illustrated my clampk as compris- 25y ing the gripping members A and B, secured together by an intermediate tensioning spring 15, said spring 15 being secured to the member A by the eye 16 and to the member B by the eye 17.

The members A and B are identical in structure except as to the length of the loo member, which is indicated by the numera 8 (in the member A) and by the numeral 13 (in the member B).

The U-shaped body 5 is provided with the hooks G, the neck 7, the long loop 8 and short loop 9, all formed from a single piece ot wire. Likewise the member B comprises the U-shaped body 10, having the hooks 11, the 40 neck 12, the long loop 13 and short loop 14.

Assembled as in F ig. l, the device has its greatest spread between the hooks 6 and 11.

ln Fig. 2 the clamp has been shortened by to shitting the eye 17 into the loop 14.

Fig. 3 illustrates still greater shortening, the eye 17 being shifted back into the loop 13 and the eye 16 having been shifted into engagement with the loop 9.

In Fig. 4 l illustrate the shortest possible adjustment of the members, the eye 16 enn gaging with the loop 9 and the eye 17 en gaging with the loop 17 Mode of operation..

The clamp thus described is intended to be used upon the bottom of a table or ironing board, the top of which table or ironing board is provided with a pad or cloth covering or both, and the edges of which pad or covering extend into contact with the outer edges of the table or ironing board. The clamp of my invention is then applied by being placed beneath the covered structure, the hooks 6 and 11 extending upwardly and holding the pador cloth in contact with the edge ofthe board or table.
